Lab 5 - Torque Methods: To complete this lab, we first put tape across a door and marked out the 10cm, 40cm, and 70cm marks. We then opened the door about 45° and marked the position on the floor. Then, we pushed the door closed at each of the marks on the tape and recorded the force using the force sensor on the IOLab. The materials needed for this lab were: Tape Marker IOLab Door Computer
Results: Question 1: It is important to hold the IOLab perpendicular to the door because if the IOLab is not perpendicular, the recorded force will not be accurate. As we can see in equation 8-18, T= rFsinθ, only the perpendicular component of the force exerts a torque about the pivot. Question 2: As I push the door closed, the door hinges are on my right. Therefore, the torque I am applying has a direction that is clockwise and negative. Question 3: Force at 40 cm: (23.1±0.3)N Same torque at 10 cm: Same torque at 70 cm:
Force measurements (Question 4): 10 cm: F = (25.27±0.05)N 40 cm: F = (23.1±0.3)N 70 cm: F = (23.0±0.1)N
